Nemesis: Retaliation - Sangrevores Expansion

With some of the attacks, you will get special infection cards (added next to your special objective face down) that only you can see. Most of the time, they will be neutral - but sometimes, they can transform you into Hemodyne yourself and shift your objective. Contamination cards are changing. Instead of a standard contamination card that will take a slot - you will actually get some unique ability representing your character getting mutated. This will happen only with contact with Crimson Despot or Blood Spectres.

Those cards will give a toolset for players to increase negative interactions - only if they wish for it. But combined with the possibility of them being turned, it will add new layers of paranoia to the game.
